This invention relates to the starting arrangements of -internal combustion oil engi'nes.

In multicylinder internal combustion oil- 5 engines provided with compressed air startstarting apparatus to their operation by the apparatus for the fuel operation ofthe engine. Such a starting operation offers no difiiculty if the levei or other controlling member whichefi'ects the starting of the en-' gine be provided separately from the-regulating'andfuel feeding device of the fuel pump, which works simultaneouslv for all the cylinders. If the operation of starting and'that of. regulating the feed of the fuel pump-is to be carried out by a single organ, then for every cylinder group one of these double acting organs for starting and working would be necessary. Such an arrangement would require not only that both hands of the operator be used simultaneously, since there would be at least two groups of cylinders,

' but furthermore his attention would have to be particularly directed to seeing that always the same amount otfuel be fed to each so of the cylinder groups, in order to avoid irre ular stresses on, or overloading of, the difierent groups of cylinders. According to the present invention the undesirable exertion and fatigue thus imposed upon the opas'erator is avoided by placing the control organs or members for actuating the engine so close together that they may be joined or coupled directly and immediatelyby a simple pin or bolt coupling or' other suitable cou- 40 pling means. In'accordance with this invention it is desirable so to constructthis coupling nieansthat the coupling bolt or pin that is 'slidably mounted in the handle of one of saidlevers, can he slid into a bore in the handle of the other lever without becoming disengaged from the first lever. The thus coupled two levers,=however, are each pro,-

vided with a lockingpawl adapted to engage a toothed segment and thus hold each lever 0' against movement until said locking pawl 204,329, and .in Germany June 23, 1927. p

is manually disengaged from its segment. Where the two levers are thus coupled, therefore, it would be necessary, before the coupled levers could be-moved, first to disengage the twolockingpawls from their respective segments, which is a'very inconvenient and cumbersome operation. In order to avoid this disadvantage, the arrangement may be such, that when the controlling members or levers are coupled, the coupling means, such. as the bolt in this instance, on the one controlling member or lever, renders the locking means, in this instance the pawl, of the other controlling member or lever, inoperative, so that the locking in position of the two controlling members or levers can be effected by only one locking means or pawl.

In the drawings one illustrative embodiment of the invention is shown diagrammatically.

Fig. 1 shows the'arrangement of the working devices of an internal combustion oil engine according to the invention; Fig. 2- shows a longitudinal section, when the coupling means or bolt is disengaged;

Figs, 3 and 3 show corresponding views when the coupling means is engaged;

- Fig l is a front elevation of a machine embodying the present invention, showing the two gearings in their, relation to'the two cylinder groups.

The levers controlling the two gears for the two groups of cylinders are designated by al a respectively.

In Fig. 1 the lever a"is shown in an opera- 'tive position which corresponds to aposition in which half the full fuel su' ply is delivered to the engine. Line 0-II corresponds to the full supply of fuel, and line 0-1 corresponds to the position in which no fuel is sup lied to the engine, while line o- II corresponds to the startingposition, inwhich the pawl 12 of lever a engages the teeth of segment 0 the roll f of the starting roll carrier g naturally has moved out of operative,

position relative to the starting cam h, by operation of the levers a, e, and thus the starting valve 71 remains closed. In the meantime the governing cam disc is, which is connected to lever a acting through roll 1 and levers or connecting rods m, has fed to the fuel pump 0 a certain amount of fuel. In order to actuate the two levers from I to III, namely from stop to full load, withone hand and always to feed the same and equal amount to the fuel pump, a pin. or bolt 9 is provided in the handle 12 of lever (1*. This bolt 9 carries on its end a button or head r, which can be pressed against the action of a spring 8, into a corresponding recess t in the handle 12' (Fig. 3). It is retained in this position by a pawl M, which can be for. that purpose brought into engagement with a groove g in the bolt q. In order to bring the bolt 9 into position to engage the recess t, as shown in Fig. 3, the pawl b must be brought out of the position according to Fig. 2* into the position according to Fig. 3 Only in theposition according to Fig. 3 *can' the bore b of the pawl b be brought into alinement with the recess t. In the position according to Fig. 3 the pawl b is disengaged from its segment 0 by engagement of bolt 9 in its bore 6 whereby it is held out of engagement with its toothed segment, and the operator, holding grip p of lever a and releasing the pawl b of said lever, can bring the coupled controlling members or levers a and a into any desired position. If the internal combustion oil engine is to be started, lever a is uncoupled from lever a byzpressing on pawl u, and bolt 9 then snaps out of the recess t by action of spring 8.

By turning levers a a into the position 0II, the engine will be started. As soon as the first rotations have taken place, preferably one of the two levers, for instance lever (1 is brought into one of the working positions between I and III, past the stopping position 0I. As soon as the firstignitions of the cylinder group corresponding to lever a take place, lever a is brought from starting position over into the working position already occupied by a Then, by bringing the bore b of pawl 6 into alinement with the recess 2. and pressing on head or button 9 ,-the bolt 9 can be caused to engage said bore 6 and recess 2?, so that the two controlling members or levers a and a are coupled, and the pawl 6 being thus held out of engagement with its toothed segment, the two levers a a can be brought into any desired .position by manipulating the pawl 5 The starting rods are indicated by z in- Fig. 4.
